Powys Wenwynwyn

Powys Wenywynwyn was a medieval Welsh kingdom that existed from 1160 to 1283, with Welshpool serving as its capital. Owain Cyfeiliog was its first ruler after Powys Wenwynwyn split from the Kingdom of Powys, and it became bitter rivals with the Kingdom of Gwynedd. Powys often allied with England against Gwynedd, including during Llywelyn ap Gruffudd's rebellion; Powysian troops assisted the English in defeating and slaying Llywelyn. In 1283, Powys was dissolved by an act of Parliament and became a part of England.
